The rumours about Windows possibly being ported to ARM has left a lot of people bewildered; why would you port Windows NT when Windows CE 6.0 is a perfectly capable operating system? Putting all the pieces together, it's actually quite clear why you would want Windows NT on ARM: servers.

Still does not make sense. The form factor is not that important. Not important enough to convince Microsoft to port Windows Server 2008 and everything else over to ARM. Atom Boxes can get small. I don't think small or home businesses would actually not buy such a useful device because it was a freaking inch too wide, high or deep for their tastes.
